Red Sea Berlin Airlift Internal Protein Skimmer
Information

The Berlin Air-Lift is a high performance, low cost internal skimmer based on the Berlin Triple-Pass principle. The Air-Lift is powered by a lime wood air-stone attached to an external air pump (not supplied), these compact units are easy to install and maintain.

The triple-pass is combined with a powerful Venturi air injector, greatly enhancing the efficiency of the skimmer. Air bubbles and protein rich water are concentrated in the narrow inner tube, ensuring good mixing and maximum surface contact. The air/water mixture swirls up the inner tube into the wider reaction chamber, causing a relaxation of the turbulent water and separation of the protein rich foam at the water surface, which rises into the collection cup. The air bubbles move down the chamber by the force of the water current until reaching the air return skirt located at its base. The skirt effectively enlarges the diameter of the chamber, eliminating the downward force on the air bubbles. The bubbles then rise up through the chamber against the downward flow of the water (counter current), causing great turbulence and increased contact time. The Venturi air injector produces a consistent quantity of fine air bubbles, ensuring a large surface area for collection of waste materials.

WORKS GREAT AFTER BREAK-IN...

Comments:This cheap skimmer works great, but after a lot of tweaking, which took about a week for me. I used a whisper 40 air pump and eventually stopped using the air valve adjuster since it required daily tweaking to properly skim. Although, after the break-in and tossing aside the valve, it pulls out a good amount of skimmate for such a cheap skimmer. Other than having to change out the air stones every 4-6 weeks and the difficult initial break-in period, this skimmer is awesome in value and efficiency. Just make sure to get a strong air pump.

Comments:I have 2 of the 90s in my 75 gallon tank. Once you figure how to maintain them, you will realize that they are the biggest bang for your buck. You can often find them for $20.00 at stores that are discontinuing them. The only place I can find the limewood that will fit, is here

works great

Nice!

Comments:The Red Sea Berlin Airlift is great! Although it is to small for my 55 gallon tank! I'm sure it would work great in a smaller tank. Very easy to set up. Only thing I suggest is having a pump with some kind of adjuster to regulate the air pressure coming out of your pump. Other than that it has worked perfect! THANKS RED SEA BERLIN AIRLIFT!!!!

Comments:I was looking to change out an older and louder injection skimmer and thought I would give this a try. This is a great skimmer when used with a good air pump. I have been using this skimmer on my 55 gallon tank and it pulls gunk from my tank daily. I would recommend this skimmer.

Comments:although I am new to saltwater this skimmer seems to work very well especially for the price. I have mine placed in my sump and it pulls alot of skimate. set it and forget it no hassles in readjusting after break in. make sure to get a powerful/adjustable air pump though.

Very Satisfied

Comments:I chose this model because of all the horrible reviews of the venturi powered hangons.Within 24 hrs I had about 1/4 cup of nasty skimmate! This product seems to work really well! Only drawback is it has to go inside the tank or in a refugium. But can be easily hidden as I opted for the corner of my tank. Great product!

Comments:A great protein skimmer! I was concerned with putting the skimmer in my tank. I thought it was going to be big and ugly in the tank. It is actually pretty cool to look at when its on. I have A 75 gallon tank, this is my first saltwater tank. I have a fish only w/ live rock and live sand. I was looking for a cheap skimmer that didnt require a sump, also I wanted to stear clear of the hang on skimmers. I heard plenty of bad reviews on hang on skimmers. So I found the berlin airlift and I am completely satisfied with it. It gets the job done for my application. Also wanted to thank you guys, this is the second Item I have orderd and both items were handled with care.
